HOOK.

Specification of Letters Patent.

Patented June 9, 1908.

Application filed March 19, 1908. Serial No. 421,991.

To all whom it may concern.'

Be it known that I, BERTHAL DALE-OWEN HAvENs, a citizen ofthe UnitedStates, and a resident of El Paso, in the county of El Paso and State ofTexas, have invented new and useful Improvements in Hooks, of which thefollowing is a full, clear, and exact description.

This invention relates to hooks such as are used for supportinggarments, and more speciically the invention concerns itself with theconstruction of a folding hook which normally holds itself in a foldedor closed position, so that the hook does not project from the supportto which it is attached. In this way the hook is especially adapted foruse where the space is limited, as, for instance, in theaters where itwill. be attached to the backs of the chairs.

lhile the hook is especially adapted for use as suggested, it may beused as an ordinary hook where the space is unlimited.

The invention consists of novel features and parts and combinations ofthe same, as will be more fully described hereinafter and then pointedout in the claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a perspective of the hook, representing Athe same in itsfolded position; Fig` 2 is a plan showing the upper end of the hook;Fig. 3 is a longitudinal vertical section taken through the hook, andFig. 4 is a rear elevation of the device.

Referring more particularly to the parts, 1 represents the case of thehook, the body of which is formed into a substantially rectangular boxthe outerface of this box is open, so as to form alongitudinally-disposed slot 2, as indicated most clearly in Fig. 3. Thebody or box of the device is formed integrally with flanges 3 and 4 atthe ends thereof, having openings to receivefastening devices 5, asindicated in Fig. 1.

In the lower portion of the case there is pivotally attached on ahorizontal pivot-bolt 6 an arm or lever 7, which is preferably bent, asshown, at its inner end and formed with a web 8. This hook is pivoted inthe lower end of the slot 2 and is adapted to fold into the slot whennot in use, as indicated in Fig. 1.

In order to hold the hook in its folded position in the upper end of thecase, I provide a bolt 9, the head of which is countersunk, as shown.This bolt depends longitudinally within the case and is provided withthreads 10 at its lower extremity, to receive an adjusting nut 11.Slidably mounted on the body of the bolt 9 is a hanger 12, whichconsists of two side bars 13, connected integrally above by a cross-bar14 through which the bolt 9 passes. Between the cross-bar 111 and thenut 1l a helical or coil spring 15 is placed around the bolt, asindicated in Fig. 4. The width across the nut 11 is substantially equalto the distance between the bars 13 of the hanger, so that the hangeroperates to prevent the nut from rotating and also operates as a guidefor the nut, as will be readily understood.

The lower end of the hanger 1.2 is connected pivotally by a shackle orlink 16 with the aforesaid web 8. From this arrangement it will be seenthat the spring 15, which is a compression spring, normally tends tohold the hanger at the extreme upper end of the case. In this positionthe link 16 operates, through the web 8, to hold the arm or lever 7folded upon the case, as indicated in Fig. 1.

The upper or outer end of the arm 7 is formed into a hook 17, whichterminates in a ball 1.8, and this ball seats upon a buffer 19, mountedin an opening 2O in the flange 3, as indicated in Fig. 3. ber, leatheror similar material. It should be understood that, on account of thisbuffer, if the arm 7 is suddenly released it will come to its foldedposition substantially noiselessly and without jarring the parts of thedevice. This is especially advantageous when the device is used intheaters, as suggested.

The tension of the spring 15 may be adj usted by applying a screw-driverto the head of the bolt 9.

In Fig. l, on account of the slot 2, the arm 7 is stowed out of the pathof a'body moving past the device and there is no projecting part, as inan ordinary hook, which could operate to interfere with a passing body.

In order to open the hook it is only necessary to seize its up er endwhich projects above the casing anc pull it outwardly and downwardly.

As indicated in Fig. 3, it will be observed that the lateral bend of theinner 'end of the arm operates to limit the downward movement of thearm, as will be readily understood.

Having thus described my invention, I

This buffer 19 is of rub-- claim as new and desire to secure by LettersPatent:

l. In a device of the class described, in combination, a case, an armpivotally attached in the lower portion of said case, a hanger withinsaid case, a spring tending to move said hanger, and a member connectingsaid hanger with said arm and adapted to fold said arm upwardly.

2. In a device of the class described, in combination, a verticallyelongated case, a hanger guided longitudinally in said case, a springtending to move said hanger upwardly, a pivoted arm connected with saidhanger and adapted to be folded upwardly thereby, and means foradjusting the tension of said spring.

3. In a device of the class described, in

, combination, a vertically elongated case, a

bolt having its head mounted in the upper wall of said case and adaptedto be adjusted, a nut on said bolt, a hanger guided on said bolt, aspring between said nut and said hanger, and an arm pivotally mounted insaid case and connected with said hanger, whereby said spring tends tofold said arm upwardly against said case.

4. In a device of the class described, in combination, a verticallyelongated case, a bolt disposed longitudinally therein and havingthreads, an adjusting nut on said threads, a spring seating on saidadjusting nut, a hanger guided on said bolt and on said nut, an armpivotally attached to said case, and a link connecting said arm withsaid hanger, whereby said spring tends to hold said arm in a foldedposition.

In testimony whereof I have signed my name to this specii'ication in thepresence of two subscribing witnesses.
